Eer the depetlijng'etween' `tvirelmf chambers of the valve casingv there must therefore be an elevation which forms a small safety distance from the poi-nt 'at which the rising and -falling Ywater -levels encounter each other. This elevation idetermines the height ofthe Walls of the valve casing. It has been found that the said, j helghtcan be lessened by altering the rec- III', IV, V and VI, the containerT112h'as-1` :VII-I.

"and, 3 o f these drawings, thecontainers 112 vand 113' arr'e turned to the=` left. g Conse-V quently the water of the chambers I, I I, VII'Q- and VIII, :communicating with the container 112, is at high level, and atlow level in the c hambersIII, IV, V and VI fowing to their communication wit-l1-jv;t-he -container 113.`

In reversing-the position jof the containers 112, 113,' the former moves first into its vertical position and ,then to the other side until, after passing through anI angle of 60, it reaches the same inclination at the right as it previously had at the left.. Dur-AA ing this movement, theccont'ainer 113 passes j from its lowest position -to-that previously occupied by the container 112. the container 113 has already reached the .position .for the highest water level,.t"'which 'has also been communicatedfto the c :lu'i`m-bers not beenrelatively lowered so thatthe 'water has remained in the chambers'I, II',.VII and l chamberhas first slightlyincreased dui-in thel movement through an angle of `60Q an"d has subsequently fallen vto" its .former level. 1 Only after'thewater level in the ch'g'imbe'rs.V

Consequently -the meeting: between thel water levels has taken place at a. *point much nearer the cover-0f the valve 'casing thanthat occurring in the arrangement described in the specitiat-ion Letters:Patent No. 1029696.l As a result, .the walls of the valve casing can'bemadel lwer and 4with' the" original .passage-opening 'for the gas, the total height of 4saidcaslng can. be ,reduced sot-hat a smaller volume of. Water will be required for `the reversing: operation, thereby enabling the parts whic to be of smaller size than heretofore. v,

I Figs. 3 and 4, show a constructional form in which the discharge pipes 121 and 122 arranged external of the -V-shaped pipe 114 to which the upper ends of said pipes are connectedbelow the containers 119J and 113 respectively and with which they rock." vThe' lower ends of the discharge pipes 121 and 122 are secured in a single turning head 127 now '.bers'I, II, lVIL'and YVIII v ofthe casing- 9 5 131f and -withirhe chambtrsAv I, ngfvnand VII-If 'of the .casing .131.*The pipes 132 and 133=arelitted with a' pipefconnection 134 'i fitted withha weight 146. -mufch the` same as previously described w1tl1 conduct the. water Y concentricallyarrangedto the sockets 115er the pipe 114'-, thevwater escaping fronl said head 127 into. a drain pipe.

.To enable air .to enter readilythe containe'rs while theivater is being discharged,

or to escape therefrom while water enters 'such containers, andthe movement of the water be facilitated, openings 128 are pro- Avided in the upper portions-of the containers' l112 and 113.

. I tjisv not'absolutely necessary to have-'an angle'of 607 between the arms o fl the pipe` 114, but it willl not'allow the water-'level in the full cha bers to fall before the empty .chambers are 'filled with water.

` `With the third example 'of construction as shownV in Figs. 5 and .6, the reversing of the lowsjofthe'gas and the air in theregenerative fu r nace.. is regulated by two valves constructed and operating in the 'same manner as lthe one hereinbefore .de-

.scribedf The valve .casing 131 and 1.13.1'- are divided into chambers Iv to VIII and It to VIIIa respectively. The chambers-III, IV, Wand Vini theeasing 131 communicate .a waterinlet vpipe 132 which also branchesv 0E into the` chambers III, IV?,

The pipes-'132,a-nd 133 f leadi'ngto'theicontainers 136 and 137 respectivelythrough vthe -intervention of thell-shaped fr oclting pipe v138, the arms 139 Iand 140 of which .form an angle of about .60ov with one another. Within` the arms areV placed't-he outlet pipes 141 and 142 respectively, the .outwardly projecting ends of which 'discharge into drains 143 and 144 respect-ively.` T he containers 13G and 137 are separated fromea'ch other by .division wall 145fprovidedin the apex of the arms 139 and'140. .Tocounteract the weight ofthe waterand the containers thepipe 138 is The Vaction is reerence to the other constructional forms. In the drawingthe pipe 13,8 1s shown in its Amiddle position.V By tu ning the latter for about 60. toward the right so as to bring the arm 140 into a horizontal position and -casings'131,:1nd/131Q lThe air enters .firstinto the chamber VIIiIand'flows beneath thewall 149 into the chamber 'VIIIEL and thence through the flueslO into the regeneratve furnace. 'The rreturn takes` place through .the flue 152i into the lchamber I'f,y and beneath the wa'll'153, into the chamber IIa and finally into the chimney flue 151. By turning the' V-shaped pipe 13S' through 120O to theleft so as to bring the arm 139- into a horizontal position, the container 136 andv the communicating chambersy III, IV, V, VI and III, IVa, Va, and VI will attain the lowest water'level, while the water level in the other chambers and4 he'container 137 i rises. Both ga's' and air will 'nowflow through the chambers III, IV, and so .forth as also through the chambers IIIa, IVa a'nd so forth so that the gas enters the regenerative fiirnace through the flue 152 while air passes through1 the flue 152", the-return taking place through the flues 150 and 150 re"` spectively. The regulationof the water levels' in the gas valve and in the air valve is thus controlled by one'and' the same mech-4 anism namely the reversing device-136, 131, and 138. v l

Having now particularly descfibed 'and ascertained the nat-ure of my said invention and in what manner the same is to be performed, I declare that what I claim is: 1..A regulating and reversingapparatus comprising in combination, a rocking device 'having tubular ari'nsdisposed at -an angle of.4

less than 90O to each other and having containers at 'one extremity of each of said arms, said arms being rigidly connected together at their other extremities and swingingly pivoted to a third tubular member/.lso that in reversingdlie position of the containers', the container which' ist being lowered will have to pass itsliighest position before .lreacliing its final positionandshall keep apiproxlniately its highesti position unt-il the container which is 'being lifted shall have reached its lii'ghestpo tion.
